Slant six cam

I am always happy with manufacturers making parts for the slant, but the Comp cam has some bad things about it as mentioned earlier threads. The cam gear is hardener and will break your cam gear prematurely. Also, the cam is center lined way off to get any decent low end torque. I don't believe either of these issues has changed despite a lot of complaints from slant six.org members. I got mine 20 years ago and replaced it with one of the last Mopar ones available from direct connection. Same specs as the Comp, but way better to drive. Talk to Doug Dutra percent Elgin or Erson cams. They will fix you up right.
And yes, bigger valves and bowl porting will get you more power.
Good luck and keep us posted!
